Specification of Letters Patent.

Patented J uly 4, 1911.

To all whom it may concern:

Be it known that I, EDWARD Onson, a citizen of the United States, residing at Jasper, in the county of Pipestone and State of Minnesota, have invented new and useful Improvements in Grain-Shockers, of which the following is a specification.

This invention relates to shock formers, and has for an object to provide a pivotally mounted shock receptacle having its longitudinal axis normally in a forwardly and downwardly inclined position and movable from such normal position to a substantially vertical or dischar ing position, and to rovide simple and e cient means for hol ing the receptacle in bundle receiving or bundle discharging positions.

A still further object of the invention. is to provide a shock former designed for attac ment to a binder so as to' be moved therewith on its travel through a field and to provide an improved carrier'receiving the bundles from the binder and conveying them to the forming receptacle.

In the drawings, forming a portion of this specification and in which like numerals of reference indicate similar arts in the several views :Figure 1 isa s1de.elevation of my improved shock former showing the receptacle in bundle receiving position in full lines and in bundle discharge position in dotted lines. Fig. 2 is a top-plan view ofthe form r showing the receptacle in bundle receiving position. Fig. 3 is a top plan View showing the receptacle in bundle discharging position. Fig. 4 is a front elevation showing the receptacle in bundle receiving position. Fig. 5 is a similar View showing the receptacle in bundle discharging position. Fig. 6 is a side view of the receptacle in discharge position, the bundle carrler being removed for the purpose of clearness, the receptacle being shown in receiving position in dotted lines. Fig is a fragmentary view of a portion of the carrier illustrating the clutch mechanism. Flg. 8 is a detail section taken on the line 8-8 of Fig. 7. Fig. 9 is a detail section through" the upper portion of the carrier. Fig. 10 is a detall section through the lower portion of the carrier. Fig. 11 is a side elevation of a ortion of the receptacle showing the weight arm and its actuating portlon opposition.

'eratively associatedwith the receptacle to -move 1t to bundle discharging position.

The shock former herein illustrated is constructed with a view of permitting it to be attached to any well known form of gram binder, (not shown), and it preferably consists of a forming receptacle 1 which is pivotallymounted, as shown at 2, on a wheeled'frame 3.

The receptacle 1 is provided at its front end with a bundle receiving opening 4 which is located slightly below the highest point of the bundle carrier 5 when the receptacle is in bundle receiving position. The receptacle is rovided at its opening 4 with a swingin c osure forming member 6, the said mem er having connected therewith one end of a cable 7 or the equivalent thereof, the opposite endof the same being connected with a stationary actuating element 8 at the forward end of the frame 3. The 'purpose of the connection 7 is to hold the member 6 in an open position when the forming receptacle is in bundle receiving Stops 9 are carried by the receptacle 1 and they are located preferably near the bottom of the bundle .receiving opening. These stops are designed to en-' gage the member 6 when the latter is in a position shown in Fig. 1 so as to limit the movement of such member in one direction. The actuating element 8 is provided at its upper end with a head 10 which is designed to be engaged by the hook 11 on the member 6 so as to limit the swinging movementof the receptacle and to hold 1t in a vertical position when dischar ing the bundles. The member 6 is provide? w1th stops 12 to engage the sides of the receptacle adjacent to the bundle receiving opening 4 so as to limit the movement of the said member 6 in one direction. The member 6 supports a presser-head 13 which is located at the upper end of a leaf spring 14. On movement of the receptacle to its vertical position the member 6 will be engagedby the actuating element 8.

At the rear, the receptacle is provided with outwardly swinging discharge gates 15. These gates are normally held in their closed position by leaf springs 16 which are secured to the part 17 of the rece tacle. To hold the gates positively locke when the sition, I provide the receptacle with "a keeper 23 which is designed to be engaged by a pivotally mounted latch member 24 on the frame 3. A spring 25 exerts its tension against the latch member 24 to hold it normally in engaged position.- A controlling rod 26 'is secured to the latch member and it is designed. .,to be manipulated manually 'to move the latch member to its released position. To move the receptacle automatically to bundle receiving position on release of the latch member 24 from the keeper 23, I provide a weighta-rm 27. This arm 27 is pivoted to the frame 3; at one side thereof and at one end the arm is provided with an actuating finger 27 toengage the finger 28 on thereceptacle. The opposite end of the arm 27 is provided with a suitable weight 29'. To hold the receptacle in receiving position I provide the' latch member 24 with a retaining portion 30 to engage the keeper 31 on the receptacle. When a s'uflicient number of' bundles have been conveyed to the receptacle to form a shock, the latch member 24. is withdrawn and the receptacle is moved manually to its vertical or bundle discharging sition, whereupon, the latch member is al owed to return under action of the s ring 25 to lock the receptacle in this positlon. When the shock has been deposited. the latch member is again withdrawn and theweight 29 restores the receptacle to its receiving position. The stops 9 are provided with hooked ends 32 to engage the 'front bar 3 of the frame 3 to stop the receptacle when it has reached its verticalor discharging position.

construction which may be found most decarrier comprises lower driving sprocket gear wheels 34 and upper driven sprocket gear wheels 35. The'upper and lower gear wheels are connected by carrier chains 36.

- These chains are s aced apart, as shown, and

they are connecte with each other by horizontal rods 37. These rods are pivotally 'mounted in suitable bearing members 38 on the chains. The driving sprocket wheels .34 are supportediby a shaft 39 which is mounted in suitable bearings 40 on the frame 3, and as illustrated, th1s shaft is provided 'at one end with a loose drivin sprocket gear wheel 41 which is connecte with a drive The carrier 5 may be of any well known chain- 42,. The drive chain 42 can receive its power from, any suitable' source, (not shown). A sliding clutch 43 is mounted on the shaft 39. This clutch comprises spaced fingers 44 and a grooved collar 45. The collar 45 is operatively connected with a lever 46 which is mountedfor horizontal pivotal. movement on the frame 3. A spring 47 on the frame 3 bears against the lever 46 so as to hold the fingers 44 of the clutch normally extended into the spaces between the spokes 48 of the sprocket wheel 41. A clutch actuatin rod 49 is pivoted, as at-50, to the receptace and at the other end the rod is connected with the lever 46 so as to move the same against the tension of the spring 47 on movement of the forming receptacle to its bundle discharging position. From theconstruction just described it will be seen that when the'receptacle is moved to its vertical position, the sliding clutch 43 will be actuated so as to throw the carrier belt out of gear.

, The frame 3 is provided with a bundle receiving rack 51 which is located at the bottom of the carrier 5. This rack consists preferably of suitably spaced bundle supporting members 52. The central portion of each rod 37 of the carrier is provided with a lip 53 to engage the curved portion 53' of the central frame forming element 54 of the carrier. This curved portion is located at the lowerend to engage and to cause the fingers 55 of the rod to assume their operative positions immediately at the beginning 0 their upward movement on the carrier belts. The'bottom of the receptacle is formed preferably of a series of parallel spaced rearwardly extending tines 50. .When th receptacle is in shock discharging position the keepers 18 will be released from the latch members 19 and the gates of the receptaclewill be free to. open under resistance of the bundles. Stops 57 are carried by the receptacle 1 and they are designed to engage the frame 3 to limit the movement thereof in one direction when the receptacle is in the dotted line position shown in.
